Specific implementation mode
Operating process to make patent of the present invention realize is easy to understand with creation characteristic, with reference to specific embodiment party
Formula, patent that the present invention is further explained.
Spray head nozzle includes conical diversion trench 1, fluidic channel 2, hemispherical nozzle 3, steel band 4；Shower nozzle is special
Sign is：1 arrangement mode of conical diversion trench is in-line arrangement, and the spacing of adjacent two conical diversion trenches 1 is 80mm；Cone is led
The bottom circular diameter of chute 1 is 40mm, is highly 15mm, thickness 2mm；2 throat diameter of fluidic channel be 10mm, a height of 20mm,
Thickness is 2mm；A diameter of 4.5mm of hemispherical nozzle 3, quantity are 5, and blowing angle is 30 °, thickness 2mm；Steel band 4
Immediately below hemispherical nozzle 3, and jet expansion to the vertical range between steel band be 30mm.
By taking instant freezer plenum chamber size is 400*400*600mm as an example, plate size 400*400*2mm, shower nozzle
Middle cone diversion trench（1）Bottom circular diameter is 40mm, is highly 15mm, thickness 2mm；Fluidic channel（2）Throat diameter is
10mm is highly 20mm, thickness 2mm；Hemispherical nozzle（3）A diameter of 4.5mm, quantity are 5, and blowing angle is 30 °, thick
Degree is 2mm；Steel band（4）Size is 400*400*2mm, and jet expansion to the vertical range between steel band is 30mm.Traditional opens
Hole plate round nozzle a diameter of 10mm, thickness 2mm.The fluid of this simulation is air, has carried out following hypothesis：1. air
For incompressible fluid, 2. model is in normal course of operation, and internal flow field is considered as stable state, and 3. plenum chamber wall surface is considered as thermal insulation.
This model uses k-ε turbulence models, due to there is the variation of temperature in impact process, therefore opens energy equation.Pressure entrance side
